"cans your WordPress installation for security vulnerabilities and suggests corrective actions."
Was that meant to be an April Fool's joke? Being concerned about security, I downloaded this plugin, ran it, set my permissions to the "suggested corrective actions" and when trying to access my site, all I got were errors. I had to reset my permissions as best as I could and got it to work again.
Either this is a bad joke or awfully written code by someone who doesn't have a clue as to what WP permissions should be.
